How to check if someone's premade in League of Legends?

Question

My friends found a way to check if a person is premade in league of legends while the game is loading in through lolking. I was just wondering how they do this? Where's the link where I can check this? Thanks.

Answer 1

It's not actually via lolking. The website you're looking for is www.lolnexus.com

During the loading screen or the game itself you just type your name and the server you're on (I'm assuming NA) and click search. There will be a ton of information about the people you're playing with. The leftmost thing is premade status. When someone is premade there will be a blue or red color.
